RV Prince Madog PD15/09
Cruise summary report
|Ship name (ship code)||RV Prince Madog (74P2)|
|Cruise period||2009-05-01 — 2009-05-04|
|Port of departure||Menai Bridge, United Kingdom|
|Port of return||Birkenhead, United Kingdom|
|Objectives||To conduct 25 hour long surveys at:
1. A near-shore station, site A, 53º 32' N, 3º 21.8' W.
2. An off-shore station, site B, 53º 37.2' N, 3º 55.2' W.
Each survey to consist of; Hourly CTD profiles and discrete water sample collection at a variety of depths. Conduct 12.5 hour long time series of turbulent microstructure using the MSS profiler. Conduct high volume filtering using SAPS (Stand Alone Pumping System). Conduct a short series of CTD profiles from 5NM west to 5NM east of site A with 5NM resolution.
Also, to continue the annual sediment study undertaken by POL's coastal observatory a 12.5 hour time series of suspended sediment load was collected at near bed and near surface by filtration of water samples collected during CTD profiles.
The cruise is the first of 5 cruises in the PhiXT series which is a collaboration between POL, PML, UoBangor and UoLiverpool managed as part of the POL Irish Sea coastal Observatory.
